Had an interesting insight into the Ops of the Dash 7 a few years back.
Noticed the said beast parked up at Stanley (Falklands), so thought I'd go for a look.
They had spent a week ferrying the a/c from Canada, and were on the last leg to Rothera (Brit Antarctic base). However, they had just returned from a 6hr flight to nowhere!
Had got 3hrs S from Stanley, but had to turn back due to much stronger than forecast headwinds. Then had to carry out the NDB approach into Stanley in typical S Atlantic conditions.
Had a good look around the aeroplane. Very nice nick, lots of modern kit in the flightdeck from what I remember.
